SPECIFICATION forming part of Letters Patent No. 775,179, dated November 15, 1904.

Application filed March 24, 1904. Serial No. 199,744. (No model.)

To all whom, it nuty concern:

Be it known that I, J AMES ELLwooD JONES,

a citizen of the United States of America, re-

siding at Switchback, in the county of Mc- Dowell, in the State of Vest Virginia, have invented certain new and useful Improvements in (eke-Pullers, of which the following is a specification.

This invention relates to a coke-puller designed to be operated by machine for pulling coke from coke-ovens, and it is particularly adapted for discharging coke from beehive ovens.

The invention is herein shown as applied to a coke-puller comprising an underworking scraper operative on its instroke to loosen coke for withdrawal and on its outstroke to withdraw the loosened coke.

The object of this invention is to insure the withdrawal of the full depth of coke on the outstroke.

Figure 1 of the accompanying drawings represents a longitudinal section on line I l of Fig. 2 of one embodiment of the invention. Fig. 2 represents a plan thereof, parts being broken out.

The same reference characters indicate corresponding parts in both the figures.

This coke-puller is designed to be mounted on a machine adapted to thrust it into and retract it from the oven and swing it laterally in either direction to enable it to engage the coke at the sides of the oven. The machine shown in the expired United States Patent No. 146,936 may be used for this purpose. The coke-puller comprises an actuating-bar 10, which is preferably rigid throughout and designedto be provided along its inner portion with rack-teeth or a rack-bar 11, corresponding to the rack-bar a of said patent. This bar is provided in its front portion 12 with a longitudinal slot 13 and at its front end with a rack 14:. A scraper is disposed at the outer end of the bar 10 and in the form shown is adapted to slide thereon. This scraper is hollow and of wedge-like form and comprises a bottom plate 21 of a breadth equal to the desired width of the scraper, an inclined top plate 22, which extends upwardly and rearwardly from the front edge of the bottom plate, and a back plate 24, which connects the inner edges of the bottom and top plates and constitutes the thick side of the wedge-like body. The top plate is provided with a transverse slot 23, and a transverse pintle-rod 25 extends across the scraper along the slot, resting in pintle-sockets 26 and 26. The scraper is provided with a hollow shank 29, having a cross-bar 29, which extends through the slot 13, and with cars 26 and 27, projecting inwardly from the back plate 24.

The scraper when constructed as shown is provided with an adjustable coke-holder 30 for holding the coke on the outstroke. This coke-holder may be in the form of a swinging plate 31, having a pintle-socket 33, disposed on the pintle-rod 25. This swinging plate in normal position lies over the outer face of said top plate below the central slot therein. The front end of this swinging plate is preferably beveled to coincide with the bottom of the scraper.

The means for adjusting the coke-holder 30 into operative position when constructed as shown comprise a toothed segment 35, attached to the socket 33 and meshing with a pinion 40. This pinion is engaged by the rack 14 of the bar 10.

In the use of this coke-puller it is preferably mounted on a machine similar to that shown in said patent, or an equivalent thereof. and retracted therefrom by the machine or by hand, if desired. The drawings show the coke-puller in position for an inward thrust. On the inward stroke the wedge-like scraper moves over the bottom of the oven underneath the caked mass of coke a suflicient distance to make a proper drawing thereof, and it may be of suilicient thickness to lift the coke under which it passes and break and separate said coke, or more or less thereof, from said caked mass. \Vhen the motion of the bar 10 is reversed, the said bar is drawn backward and the scraper remains stationary under the weight of coke behind it or under the action of a positive stop for the purpose until the front end of the slot 13 in said bar The coke-puller is thrust into the oven engages the cross-bar 29 of the shank of said scraper. During this backward movement of the bar the coke-holder 30 is swung into upward position by the action of the gearing, whereby the main portion of the coke immediately above the scraper is grasped or held for the outward stroke. The backward movement of the bar 10 is continued after it becomes locked with the scraper, and the latter is drawn backward While the coke-holder is in open position. The scraper with its holder so adjusted pushes the coke behind it out through the door of the oven. The first few strokes of the coke-puller are preferably in a direct line, it usually requiring two or more drawings to remove the coke throughout the diameter of a coke-oven. lateral thrusts of the coke-puller are made, first to one side and then to the other, by means of the machine on which the coke-puller is mounted. On the inward stroke of the bar 10 the gearings between it and the coke-holder operate to close the coke-holder.

The shank of the scraper may be in the form of an elongated bar extending back to the machine or operator and be movable independently of the weight of coke to thrust the cokepuller into operative position.

After this is done 2. A coke-puller comprising an underwork- 1 mg scraper provided with a coke-holder consisting of a swinging plate hinged to said scraper, an actuating-rack device, and gearing connecting said rack device with said cokeholder for swinging the latter into open or closed position.

3. A coke-puller comprising an underworking hollow scraper movable over the bottom of a coke-oven and provided with a transverse slot in its top plate, a coke-holder comprising a swinging plate hinged to said scraper at said slot and. provided With a toothed segment, a pinion disposed within said coke-puller, and an actuating-bar provided with a rack for engaging said pinion to swing said plate into open or closed position.
